Osmo calls their PreLoad Hydration Mix a "hyper-hydrator." This is NOT a drink mix you whip up before taking a spin around the block. PreLoad Hydration should be used only before exercise in extreme heat, intense efforts, or ultra-endurance. It's Peter Sagan's secret weapon that helped him secure the Green Jersey in the 2013 Tour de France. It's also how Sagan rides wheelies with such ease.
